Between the Isle of Palms and Sullivan's Island, water flows into and out of the tidal marshes through the Breach Inlet. With beaches on both sides, this is a nice place to walk around or relax in the sun. It is also a popular fishing spot, although the water is not safe for swimming. The highway bridge that crosses the inlet also has sidewalks and bicycle lanes. You will also see a number of very expensive houses in the surrounding neighborhoods overlooking the beach here.
